just an idea, but Poser chaches only the most recent so-many files, as set in the General Preferences (25 by default). Why not copy those contents into a more definite pool, if you want to keep them from re-doing? Just every day or so, in a start-up or shut-down script or daily task. They are just EXR image files, ready for photoshop or alike...
